The command :

The error is below :

Where-Object : Cannot bind parameter 'FilterScript'. Cannot convert the "subject" value of type "System.String" to type "System.Management.Automation.ScriptBlock". At line:1 char:12 + gci | where <<<< subject -like "UTN" + CategoryInfo : InvalidArgument: (:) [Where-Object], ParameterBindingException + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.WhereObjectCommand

I am using windows PowerShell ISE.
a workable solution is highly appreciated

Answer 1

It looks like you are using PowerShell Vs.2, that version had no support for the new where syntax.

In version 1 and 2 of PowerShell use:

gci | where {$_.subject -like "UTN"}

You need to put curly brackets around the expression and refer to any properties with the $_. prefix.

Answer 2

Peter Hahndorf has already answered this, but I wanted to expand on the error message you received:

Cannot convert the "subject" value of type "System.String" to type System.Management.Automation.ScriptBlock"

This is saying that it can't convert a string into a scriptBlock, which implies that where needs to be followed by a script block like so: {code here}

Be sure to read the error messages and try to interpret what they mean.

Answer 3

Use "-match" to find UTN that could be anywhere in the subject

gci | ?{$_.subject -match "UTN"}

If you use "-like" and nothing shows up, put what you're looking for between asterisks inside of quotes.

gci | ?{$_.subject -like "*UTN*"}
